What are the characteristics of waterproof plugs?
The waterproof wire plug is called a high-efficiency energy-saving power supply. It represents a stable power supply direction. It has become a combination of stable power supply. In the case of high frequency switches, the link components inside the waterproof plug will consume very low energy, power service Can reach 70-90%, almost twice the linear power plan.
The disadvantage of the waterproof wire plug is that the linear power regulator function is good, it can adjust the voltage rate, adjust the load, the output noise, and the ripple control, and the electromagnetic interference of the other electronic structures is simple, and the necessary response speed passes. Compared to linear power supplies, only the waterproof control program will be messy than the linear power supply, noisy, but an important advantage is that the waterproof plug has fewer features from the size and weight of the power supply function, consuming more.
This is made by the power supply under similar conditions, which greatly reduces the volume ratio of the linear power output power, and greatly reduces the capital, we don’t know the pin connections of the bracket, so it is easy to save the fault. In other words, my measurement always has a deviation, and ultimately unable to suppress the drawing PCB connector.
I think this is one of the differences between China and other countries in other countries. Not only on the chip, but we don’t do it on these details. In general, the headset has a three-stage plug. The diameter of the plug is usually 3.5mm and 2.5mm. Different diameters of plugs correspond to headphone sockets with different diameter holes. Therefore, from the perspective of system reliability, “public” and “mother” should correspond, and the pin and pin 4 should be grounded. In this case, when not inserted into the headset, place the channel input on the ground and the system is input to 0
